I N S T A L L I N G H A R D W A R E5.7.2. Connecting Fiber ConnectorsWhen connecting fibers, use fiber connectors according to the optical port type of the peer equipment connected tothe local network port module. Single-mode fiber is used for external connections of the single-mode optical port.Multi-mode fiber is used for external connections of the multi-mode optical port.Before connecting the fibers, make sure the type of the connector and the fiber are consistent with the optical porttype.Warning: When the optical port is not connected with a fiber connector or when its dustproof cover is open,invisible radiation can escape from the optical port. Do not stare into the optical port directly. Cover the optical portif there is no connector plugged in.SC fiber connectorThe 8GBIC port uses an SC fiber connector, shown in Figure 19.Figure 19 The SC fiber connector1. Plug one end of the SC fiber connector into the optical port in the module.2. Connect the other end of the connector to the corresponding device.Caution: When connecting an SC fiber connector, the switch TX must be connected to the RX of the deviceon the network, and the switch RX must be connected to the TX of the device on the network.MT-RJ fiber connector24FX ports use an MT-RJ fiber connector, shown in Figure 20.Figure 20 The MT-RJ fiber connector1. Plug the MT-RJ fiber connector in the optical port into the module.2. Connect the other end of the fiber connector to the corresponding device.34
